Design Ideas | This blue mat-like perennial looks gorgeous around rocks and landscape boulders. Use at the top of retaining walls or to soften unsightly curbs. Like a groundcover, it spreads over a very large area. Great on slopes, berms and banks to offer both color and erosion control. Though it's ideal for the traditional rock garden, it's also a natural in the Mediterranean landscape. |

Care | Thrives in well-drained, slightly acidic soil. Water deeply, regularly during the first growing season to establish an extensive root system; once established, reduce frequency. Space 2 to 3 ft. apart as groundcover; closer for faster coverage. Control weeds with mulch until plants fill in. |
